How to execute an external program - Ruby equivalents to PHP?

ruby-talk
1

PHP has these:

shell_exec -- Execute command via shell and return the complete output as a
string
system -- Execute an external program and display the output
passthru -- Execute an external program and display raw output
exec -- Execute an external program

And a few more that I don't use. Does Ruby have equivalents? I am especially
intersted in a shell_exec counterpart.

thanks

backticks:

result = `echo Hello World!`

There are a few others, like #system (I believe). Check out the
documentation for Kernel.
